2011 BMW 335i [N55], JB4 only. 3rd Gear pulls beginning roughly at 3000rpm, experiencing repeated throttle cuts with onset of WOT. Other logs have shown a slight overboost situation, a spike in LEAN AFR's, though usually show as a RESULT, rather than a CAUSE of the THROTTLE CUT. Car feels much more powerful during normal driving rather than dedicated 3rd gear pullsfor logging. LEAN AFR's do scare me however, even for a short period at onset of WOT.
